在(zai)葉輪(lun)運轉初期(qi)及所有(you)定期(qi)檢查的時候，只要(yao)(yao)一(yi)有(you)機(ji)會，都必(bi)須(xu)檢查葉輪(lun)是否(fou)出現裂紋、磨(mo)損、積(ji)塵等缺陷。只要(yao)(yao)有(you)可(ke)能(neng)，都必(bi)須(xu)使(shi)(shi)葉輪(lun)保持清潔(jie)狀態(tai)，并定期(qi)用鋼絲刷刷去上(shang)(shang)面的積(ji)塵和銹皮等，因為(wei)隨著(zhu)運行時間的加長，這些灰(hui)塵由于(yu)不可(ke)能(neng)均勻(yun)地(di)附(fu)著(zhu)在(zai)葉輪(lun)上(shang)(shang)，而造成(cheng)葉輪(lun)平衡(heng)破壞，以(yi)至引起轉子振動。葉輪(lun)只要(yao)(yao)進行了(le)(le)修理，就(jiu)需要(yao)(yao)對其再作動平衡(heng)。如有(you)條件，可(ke)以(yi)使(shi)(shi)用便攜試動平衡(heng)儀在(zai)現場進行平衡(heng)。在(zai)作動平衡(heng)之前，必(bi)須(xu)檢查所有(you)緊(jin)定螺(luo)栓是否(fou)上(shang)(shang)緊(jin)。因為(wei)葉輪(lun)已(yi)經在(zai)不平衡(heng)狀態(tai)下(xia)運行了(le)(le)一(yi)段時間，這些螺(luo)栓可(ke)能(neng)已(yi)經松動。

現階段是很多雞舍都配備了通風管，我是2013年開始用的通風管，在使用過程中，曾經出現過很多問題，成都防火閥現總結一下，歡迎拍磚交流。一，通風管的作用。1降低操作負壓。冬季沒安裝通風管的雞舍，使用小窗通風，尤其是跨度大的雞舍為了導風合理安全，使用高負壓通風。而使用通風管道，由于進風在管道內基本不擴散，低負壓下都是按照風管方向，依次從開口處出風。2位置高，出風均勻。進風雖然在管道內沒有預熱，但下落位置高，向下擴散時間就是預熱過程。3跟風機配合合理配置，值得信賴的防火閥在初(chu)始開啟風機階段，由于設計(ji)問題導致進風窗使用(yong)不安全，可以利用(yong)通風管過渡。

在(zai)空(kong)(kong)(kong)調(diao)送(song)風系統(tong)(tong)(tong)中(zhong)，空(kong)(kong)(kong)調(diao)送(song)風機送(song)出(chu)的(de)風必須通(tong)過主(zhu)(zhu)干管(guan)(guan)分(fen)配到(dao)支管(guan)(guan)中(zhong)；在(zai)排(pai)(pai)(pai)(pai)煙(yan)(yan)系統(tong)(tong)(tong)中(zhong)，煙(yan)(yan)氣由支管(guan)(guan)到(dao)主(zhu)(zhu)干管(guan)(guan)后，進入排(pai)(pai)(pai)(pai)煙(yan)(yan)風機排(pai)(pai)(pai)(pai)出(chu)。當建筑物內發生(sheng)火(huo)災時，在(zai)通(tong)風、空(kong)(kong)(kong)調(diao)系統(tong)(tong)(tong)中(zhong)，為了防(fang)(fang)止(zhi)火(huo)勢通(tong)過送(song)風系統(tong)(tong)(tong)蔓延(yan)，當送(song)風系統(tong)(tong)(tong)中(zhong)氣體溫度達到(dao)70℃時，防(fang)(fang)火(huo)閥(fa)機構上熔斷(duan)(duan)器(qi)動作，閥(fa)門(men)亦迅速關閥(fa)，切斷(duan)(duan)煙(yan)(yan)氣與火(huo)勢沿風管(guan)(guan)蔓延(yan)的(de)通(tong)路。同(tong)樣，在(zai)排(pai)(pai)(pai)(pai)煙(yan)(yan)系統(tong)(tong)(tong)中(zhong)，發生(sheng)火(huo)災時，排(pai)(pai)(pai)(pai)煙(yan)(yan)閥(fa)開啟，進行排(pai)(pai)(pai)(pai)煙(yan)(yan)，為了截斷(duan)(duan)高溫煙(yan)(yan)氣在(zai)排(pai)(pai)(pai)(pai)煙(yan)(yan)管(guan)(guan)路中(zhong)流(liu)動，防(fang)(fang)止(zhi)火(huo)勢蔓延(yan)到(dao)另一防(fang)(fang)火(huo)分(fen)區，當排(pai)(pai)(pai)(pai)出(chu)的(de)煙(yan)(yan)氣溫度達到(dao)280℃時，排(pai)(pai)(pai)(pai)煙(yan)(yan)防(fang)(fang)火(huo)閥(fa)、排(pai)(pai)(pai)(pai)煙(yan)(yan)口上熔斷(duan)(duan)器(qi)動作，閥(fa)門(men)必須自動關閉，阻止(zhi)排(pai)(pai)(pai)(pai)煙(yan)(yan)。由此可見，防(fang)(fang)火(huo)閥(fa)、排(pai)(pai)(pai)(pai)煙(yan)(yan)閥(fa)做(zuo)到(dao)了該通(tong)則通(tong)，該斷(duan)(duan)則斷(duan)(duan)的(de)隔(ge)煙(yan)(yan)阻火(huo)作用。
